SVChost.exe - k netsvcs has crippled my machine like no malwaer ever has. From what I can tell, this has something to do with Windows Update.

Nothing else unsual is running. There is no malware involved. And all updaes are installed Except I cannot update .net. I get the following error message:

"Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x86"

What can I do? I am frustrated.

Windows for home | Previous Windows versions | Performance and system failures

Thanks for the help! I followed Joel's advise above & it SEEMS to have resolved the problem. I say SEEMS, because I have seen the problem apparently resolved, only to resume again after a few days. Updated Malwarebytes showed no infection doing a deep scan.

I will be back if proble returns.... for now, issue resolved!

    FIrst, right click on Start > Search. Type SVChost.exe in the field for files to be searched for. Choose to search your primary disk drive (usually C). Be sure to use advanced search features to enable searching hidden files and folders. Click Search to begin. Look through the results for the location of the files listed. All SVChost.exe files should be located in C:\Windows\System32 folder. Any found in any other location are part of malware. Also, what is the error message you are receiving when attempting to update Net Framwork?

    OK - I deleted several copies of svchost.exe from several locations that looked harmless. Including prefetch. Prpblem remains.

    Included were a couple of copies of svchost.ext in .NET framework areas. Maybe related???

    Maybe I should post my failure of .NET to update on a seperate thread?
